Description

Technical Field

[0001] This utility model relates to the field of vibration reduction for vehicle refrigerators, and in particular to a pre-installed vehicle refrigerator that can reduce vibration of the control panel and exterior door. Background Technology

[0002] In the field of automotive refrigerators, OEM products often employ a design structure where the refrigerator lid and door are stacked to balance aesthetics and functionality. However, current low-temperature automotive refrigerators generally rely on compressors for refrigeration, and due to the operating characteristics of compressors, the door vibration problem is significant. Specifically:

[0003] On the one hand, the compressor, as the core vibration source, transmits its mechanical vibrations to the exterior door through pipelines, support structures, and other pathways. In existing designs, pipelines often use straight or simple bends, lacking effective vibration buffering mechanisms, resulting in vibration energy being transmitted to the door with almost no attenuation. The shock absorption design of the support structure (such as ordinary foot pads) has limited performance and is unable to cope with the transmission of high-frequency vibrations from the compressor, ultimately causing significant shaking of the door.

[0004] On the other hand, the market's stringent requirements for cost control make optimizations directly targeting the compressor's vibration source (such as replacing with low-vibration models or upgrading internal vibration damping structures) face significant resistance, making it difficult to implement while keeping costs essentially unchanged. Therefore, the core challenge of existing technologies lies in how to effectively reduce the subjective perception of door vibration by optimizing the vibration transmission path design without significantly increasing costs. If this technological bottleneck cannot be overcome, it will not only affect users' intuitive experience of the refrigerator's quality (such as a cheap feeling caused by door vibration and operational discomfort), but may also lead to accelerated wear and tear on door hinges, seals, and other components due to long-term vibration, thereby affecting product reliability and lifespan. Utility Model Content

[0005] The purpose of this invention is to provide a pre-installed vehicle refrigerator that can reduce vibration of the control panel's exterior door, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pre-installed vehicle refrigerator that can reduce vibration of the operating table's exterior door, comprising a refrigerator body, a compressor inside the refrigerator body, a refrigerator door outside the refrigerator body, a return gas connection pipe and an exhaust pipe connected to the compressor, both the return gas connection pipe and the exhaust pipe having a U-shaped bend structure, and shock-absorbing pads below the compressor.

[0007] As a preferred embodiment of this utility model, the end of the return gas connecting pipe near the compressor is provided with a Y-shaped U-shaped structure, the end of the return gas connecting pipe near the refrigerator body is provided with a Z-shaped U-shaped structure, and the return gas connecting pipe between the Y-shaped U-shaped structure and the Z-shaped U-shaped structure is provided with an X-shaped U-shaped structure.

[0008] As a preferred embodiment of this utility model, the exhaust pipe is provided with an X-direction U-shaped structure II at the starting end near the compressor, the exhaust pipe is provided with a Y-direction U-shaped structure II at the end, and the exhaust pipe between the X-direction U-shaped structure II and the Y-direction U-shaped structure II is provided with a Z-direction U-shaped structure II.

[0009] As a preferred embodiment of this invention, the compressor is connected to a fixed support base at its bottom, and the bottoms of several fixed support bases are connected to shock-absorbing pads, which are made of rubber.

[0010] As a preferred embodiment of this utility model, both the adjusting support frame and the guide rail groove are provided with mounting holes, and mounting rods are provided in the mounting holes.

[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0012] 1. Through the synergistic effect of the X, Y, and Z three-way U-shaped bend structure of the return air connection pipe and the exhaust pipe, and the rubber shock-absorbing pads at the bottom of the compressor, a dual system of "pipeline path buffering + support structure vibration reduction" is formed. Without modifying the compressor vibration source, the vibration value of the exterior door can be reduced from 0.45m / s² to 0.08m / s², significantly weakening the vibration and abnormal noise that users can perceive, and improving driving comfort.

[0013] 2. The rubber shock-absorbing feet have good elastic cushioning performance, which can directly absorb the vertical vibration energy transmitted through the fixed support base when the compressor is running, reduce the transmission of vibration to the refrigerator body, reduce the rigid vibration transmission generated by the contact between the support structure and the refrigerator body, further enhance the overall vibration reduction effect, and extend the service life of the compressor and door components.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] This utility model provides a technical solution: a pre-installed vehicle refrigerator that can reduce vibration of the control panel's exterior door, such as... Figure 1 , Figure 2 As shown, the refrigerator includes a refrigerator body 1, a compressor 2 inside the refrigerator body 1, a refrigerator door 3 outside the refrigerator body 1, a return gas connection pipe 4 and an exhaust pipe 5 connected to the compressor 2, both the return gas connection pipe 4 and the exhaust pipe 5 are provided with a U-shaped bend structure 6, and shock-absorbing pads 7 are provided below the compressor 2.

[0021] like Figure 3 , Figure 4 As shown, the end of the return gas connection pipe 4 near the compressor 2 is provided with a Y-direction U-shaped structure 601-1, the end of the return gas connection pipe 4 near the refrigerator body 1 is provided with a Z-direction U-shaped structure 602-1, and the return gas connection pipe 4 between the Y-direction U-shaped structure 601-1 and the Z-direction U-shaped structure 602-1 is provided with an X-direction U-shaped structure 603-1.

[0022] like Figure 3 , Figure 4 As shown, an X-direction U-shaped structure 601-2 is provided at the beginning end of the exhaust pipe 5 near the compressor 2, a Y-direction U-shaped structure 602-2 is provided at the end of the exhaust pipe 5, and a Z-direction U-shaped structure 603-2 is provided on the exhaust pipe 5 between the X-direction U-shaped structure 601-2 and the Y-direction U-shaped structure 602-2.

[0023] like Figure 1 , Figure 4 As shown, the bottom of the compressor 2 is connected to a fixed support base 8, and the bottom of several fixed support bases 8 is connected to the shock-absorbing pads 7. The shock-absorbing pads 7 are made of rubber and can absorb shock.

[0024] In practice, when the vehicle refrigerator is started, the compressor 2 begins to run and generate vibration. At this time, the vibration energy is mainly transmitted to the refrigerator body 1 through two pathways: First, the vibration at the bottom of the compressor 2 is transmitted to the shock-absorbing pads 7 through the fixed support 8. The rubber shock-absorbing pads 7 absorb part of the vibration energy through their own elastic deformation, thus slowing down the transmission of vibration to the refrigerator body 1. Second, the vibration generated by the compressor 2 is transmitted to the refrigerator body 1 through the return gas connection pipe 4 and the exhaust pipe 5. This is the core function of this design.

[0025] During the transmission of vibration along the return gas connection pipe 4 and the exhaust pipe 5, the U-shaped bends 6 in the X, Y, and Z directions play a crucial role. Taking the return gas connection pipe 4 as an example, when the vibration is transmitted to the Y-direction U-shaped structure 601-1, the flexible structure of the U-shaped bend allows the pipe to undergo slight elastic deformation in the Y direction, which consumes some of the vibration energy. As the vibration continues to be transmitted, the X-direction U-shaped structure 603-1 and the Z-direction U-shaped structure 602-1 also absorb and buffer the vibration energy in the X and Z directions through their own elastic deformation and structural characteristics. The X-direction U-shaped structure 601-2, the Z-direction U-shaped structure 603-2, and the Y-direction U-shaped structure 602-2 on the exhaust pipe 5 consume the vibration energy step by step in the three directions using the same principle.

[0026] Since the vibration energy generated by compressor 2 is fixed, it is repeatedly consumed by the multiple U-shaped bends 6 on the return gas connection pipe 4 and the exhaust pipe 5, resulting in a significant reduction in the vibration transmitted to the connection point of the refrigerator body 1. Since the refrigerator door 3 is connected to the refrigerator body 1, the vibration value transmitted to the exterior door is significantly reduced. Actual testing showed that the objective vibration value of the exterior door decreased from 0.45 m / s² to 0.08 m / s². Subjectively, users can hardly perceive the vibration transmitted by compressor 2, effectively improving the stability and comfort of using the vehicle refrigerator.

[0027] Vibration data test comparison of the exterior door body (0-800HZ), the specific values ​​are as follows:

[0028] X direction Y direction Z direction Root mean Initial structure without U-shaped bends 0.25 0.26 0.27 0.45m / s² Single return air pipe with added U-shape 0.13 0.15 0.12 0.23m / s² Single exhaust pipe with added U-shape 0.12 0.11 0.10 0.19m / s² Both return and exhaust have added U-shaped features. 0.05 0.04 0.05 0.08m / s²

[0029] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
